Odometer reading on Hyundai vehicles

I am currently working on a personal telematics project involving odometer reading. I have been successful in reading odometer values from different vehicles, however, the Hyundai cars are giving me a little bit more work. I wasn't able to find the odometer on a Elantra Touring 2011 or the Genesis Coupe 2011 (or 2012).

Has anyone done any odometer work on these cars or could give me a hint as to where I could find the odometer on those and what's the odometer format stored on those vehicles ?
